VThisy invention relates to l new and useful improvements V,in locks and more .particularly i.

to novel means for Aattaching the actuatingk'nobsonl to the 'shaft'fithe lockingbolta` Theimain object vof the present invention is the-provision ofyne'w and improved means whereby thev actuating knob may be k'quickly andreadily mounted npon the end of the shoulderportion 16` on the boltg i I: Y Y y I Y v f the door 1 ,are the plates 17 and 17 having sleeves 18Y v 4projecting from the outer face thereof, said sleeves lbeing provided with an annularv groove 19 upo'nfthe interior thereof which 1 7() ing thereto from the outer end ofthe sleeve. l' The knobs 21..,are pro-vided' with 'the usual locking bolt shaft so as to eliminate the use Yof screws-or other vsimilar fastening means forretainlng the knob 1n position end of the shaft.

f ..inotherfobject of myinvention isvthe pro? vision of improved means for engaging the knob with an attaching plate carried by the door and whereby the knob may be readily engaged with the shaft upon which the locking bolt is mounted so as to eliminate superfluous fastening members, such as screws or the like whichv are used at the'present time.

With the above and other objects in view, my invention consists in the novel features Yof construction and the combination and ar rangement of parts to be hereinafter more fully described, pointed out in the claim and shown inthe accompanying drawings, in which: r Y Fig.. 1 is a longitudinal section view Vthe locking bolt therein,

by means of the screws 5. Y

The side walls of the casing are rovided with aligned openings v6l through w ich the shaft'7 extends, said shaft also extended through the openings 8in the door 1 upon opposite'sides of the casing.

A locking bolt 9 is arranged 'longitudinally in the casing 8, having a tapered end 10 at its outer end whileu the inner end is bifurcated to form the spaced armsll, each arm having oppositely disposed tongues 12 and.A

as noted in Figure 1, the arms 11 are `dis-` posed upon opposite'sidesof the shaft7.

upon the l through a lock, illustrating the position of section on the end thereof which are attached to the door Mounteduuponithe' shaft 7 andiarrangedA:

upon oppositesides of the bolt 9` are. lthe tumblers 13 Ihaving av straight-face portion",

Arranged upon cpposite sides o is provided with a transverserecess20 leadshaft-receivingsleeves 22, carrying'A pins 23 which are adaptedto be inserted through the recess 20andfen'gaged within the annular f groove 19 for` retaining thesleev'es 22 in poysitionnponl the end of the shaft 7 and olisposed within the sleeve 18. g y

,. The plate 17,'is provided with ystuds 24 at the endsthereofwhich extend into suitable transverse openings`25 in the door, said studs sov having an'internallyl threaded bore 26' to re-l y* ceive the connecting screw bolts 27 which'y are passed through the Sleeves 28 Vonthe plate 17 Land threaded into thebore'26. This securely connects the plates 17 and 17 andl also clamps them tightly against the outer faces ofthe door. Y In'placing the knobs the ends of the'shaft 7 ,.it will beapparent that the plates 17 and 17 will be in a loose condition andV not attached to the door kso that the outer end of the sleeve 22 may be inserted into the endv ofthe sleeve 18 with the pin 28 passing into the recess 20, after V21 in posit-ion upon" which the knob v21 isy given a predetermined'v turninginovement to throw the lpin out of Y alignment with the recess 20. V`This will po'- sitionvvthe rectangular opening in the sleeve 22 in alignment'with the end ofl theShaft 7 whichis received into the sleeve 22, as shown in Figure 2. -The pin 23 is then inlsuch a position relative tn .the recess 20 as to permit l Y turning movementl ofV the knob 21 in ,either direction for actuating the bolt 9, but will prevent the pin from being aligned with the actuating the Ibolt 9, is limited due tothe engagement ofthe inner end of thebolt with the back wall of the casing recess 20. .The rotation of theA shafti', when I .Further regarding Vthe mounting of the kgiobs onthe shaft, it will befnoted=-that atten e ch kknobhas 'beenplacedin position 'upon constructing look of this character, it elini-y inates the .use of soreWsnnjl-sirnilartastening members for attaching the knobs to the shaft and also providesjfor positive' operia ,tion of the'bolt.
